Utilization of Waste Flex in Concrete

Abstract

This research includes the result of an experimental investigation about the disposal of waste flex in cement concrete without compromising its normal strength. Solid waste management is a very critical in the present context and also going to be very great issue in future. Flex is used for different kinds of hoarding boards for advertisement and many other purposes. As its uses is increasing rapidly day by day, its disposal is also becoming difficult as it is a kind of plastic and disposing of plastic is critical issue at the present context throughout the world because it causes different types of pollutions resulting to the different diseases among the human beings as well as other living creatures on earth. In this research work, waste flex is added in cement concrete mix by making very small pieces about some percentage of cement in the mix. This will minimize the problem of disposal of waste flex and is also somewhat reducing the cost of concrete by using waste materials. We have adopted three percentage of flex in concrete mix i.e. 0 .75%, 1% and 1.5 % by the weight of cement. The concrete mix adopted for the experiment is M-25. This report includes the comparative study of compressive strength of concrete cubes containing the waste flex with normal concrete of same design mix after curing the cubes for 7 and 28 days. It was found in experiment that the compressive strength is increased at addition of 1% of flex by the weight of cement in concrete and similar strength at other two percentage of flex compared to the compressive strength of normal concrete tested after curing of cubes respective number of number of days.
